I wake up tired every morning. I'm tired at work. I usually wake up a little during lunch. Then, I'm really tired in the afternoon. Then, I'm awake for dinner, and am tired again until it's time for bed. I probably get an average amount of sleep compared to most Americans. And yet I spend most of my life tired. Is this normal? natural? a recent historical trend? It just doesn't seem right. Or should I just compare it to eating? Where I'm always hungry. But, it's a controllable hunger.
